Ser will advise the Inquisitor on how to construct a proper lyrium philter and utilize Templar abilities. If the Inquisitor completes the training and learns the templar abilities, Ser will offer the war table operation Endure, in which Ser offers to teach other members of the Inquisition templar techniques, noting they would be useful against Demons and the mages commanded by the Elder One.

Afterwards, Ser can be encountered around Skyhold and will occasionally visit Cullen where they will discuss matters pertaining to the Templar Order.
